| Abstract: | Background: A clear field of view during laparoscopic surgery is necessary to compensate for a lack of tactile feedback. A laparoscopic aspirator irrigator (LAI) is a device used for aspiration and irrigation to maintain a clear field of view. Due to its limited flexibility, it is often difficult to reach the target area with an LAI during complex procedures. The StreamFlex is a steerable prototype LAI which aims to improve the accessibility of hard-to-reach areas in complex laparoscopic surgery. This research evalu-ated the performance of the StreamFlex. Methods: Following a literature study, observational study and a survey amongst surgeons and surgi-cal assistants, indicators for performance were defined. Preclinical testing was conducted using a sim-ulated model of a hepatectomy to test these indicators. The performance of the StreamFlex was com-pared with a conventional LAI. Results: Results show an improved aspiration ratio by the StreamFlex, while being a slower tool to use. Each participant provided a SUS score for the StreamFlex through a post-simulation question-naire. The mean SUS score of the StreamFlex was 80.5, suggesting good usability. Additional feedback provided by participants was consulted to define improvement and follow-up research suggestions. Occlusion rate, irrigation, and the integrity of the StreamFlex were on par with the LAI. Feedback pro-vided by participants suggests the structural integrity and the rotary knob needs to be improved. Conclusion: The statistically significant results indicate an improved performance of the StreamFlex, compared to the conventional LAI. Based on these findings, the StreamFlex could be of added value in the operating room during complex laparoscopic procedures. It is necessary to further develop the StreamFlex and test it under a more diverse set of circumstances. In a preclinical setting, the Stream-Flex proves to be of added value for laparoscopic surgery. |
